Step-by-step explanation:
The number line is a line with marks, where each mark represents a real number.
In the vertical number line zero is in the center. The numbers above zero are considered positive and the numbers below zero are considered negative.
4
3
2
1
0
-1
-2
-3
-4
The numbers after zero start from 0, 1, 2 ...... and 0, -1, -2.....
Hence, Carlos is wrong and -4 is further to zero than -2
Given:
Irregular Shape:
Semi-circle and rectangle:
Area of a rectangle = l * w
Area of a semi-circle = (π r²)/2
Area of rectangle = 8 cm * 5 cm = 40cm²
Area of a semi-circle = (3.14 (4²))/2 = (3.14*16)/2 = 50.24/2 = 25.12cm²
4² is taken from diameter of 8cm divided by 2 to get the radius.
Total area = 40 cm² + 25.12 cm² = 65.12 cm²
Answer:
Step-by-step explanation:
External angle equals to the sum of opposite internal angles
z - 41° + z - 20° = z + 40°
2z - 61° = z + 40°
2z - z - 61° = 40°
z - 61° = 40
z = 40° + 61°
z = 101°
